If you are about to upgrade — upgrade to Spyglass. Even if you don't need the camera overlay all you need is Spyglass app only. Since version 2.2 it has an option to turn camera off to save battery power. The Commander Compass has the same price. It is maintained in the store to support existing users and to provide free updates.
After months of work the new user guide is finally available. Send your feedback to let us know what you think and how we can improve it further. Translations and the ePUB version are coming.
NOTE: User Guide is ~40 MB — stay patient while it downloads.
Meet the new videos explaining how to use main features and built-in tools of Spyglass and Commander Compass apps we shot this summer — more videos are coming soon.
